Disabling Security on http-invoker EJB for JBoss EAP 7.2

Issue

• Disabling security doesn't allow the EJB client to connect

• After disabling security with

  • /subsystem=remoting/http-connector=http-remoting-connector:undefine-attribute(name=security-realm)

  Or

  • /subsystem=undertow/server=default-server/host=default-host/setting=http-invoker:write-attribute(name=security-realm)

  I get this exception in server.log:

  ERROR [org.jboss.as.ejb3.invocation] (default task-1) {} WFLYEJB0034: EJB Invocation failed on component ServiceBean for method public abstract some.class.package.Message some.class.package.RemoteService.getMessage(some.class.package.Message): java.lang.IllegalArgumentException: Parameter 'identity' may not be null
